Hello,
Let's x the length of the second rectangle:
x/14=3/9==>x=14/3==>x=4.666666......
Answer A
The 2 legs of the triangle below are a and b. The 2 legs are called the opposite and adjacent sides respectively. The side c is called the hypotenus. The hypotenus side is the longest side of a right angle triangle.
Answer:
Step-by-step explanation:
From the question,
The total number of marbles in the bag,n(S) =10.
The number of black marbles,n(B)=7
The probability that both marbles are red means that, the first marble is red and the second marble is red.
P(1st marble is Black)=
Since Petra picked the first marble without replacing it, the total number of the marbles will reduce by 1. Same is applied to the number of black marbles.
This implies that,
P(2nd marble is black)
P(both are black)=
